Loving my new toy...
Descending set (I think that's what you call it...)
Started off at 1.32 SPL 20 (I think I even counted some 18s and 19s - must have been wrong!) and after each 10 - 14 laps I increased (decreased??) tempo by 0.02 right down to 1.20. I stopped here as I had one or two SPL counts of 24 (mainly 22-23 though).
I didn't do any timing of sets today, I just wanted to really feel each tempo and concentrate on timing, patient lead hand and my SPL.
Again was surprised to look at watch and to see that I'd swum just over 2km in my 45 minute time in the pool.
